Be it known that I, AUSTIN F. LAMB, ot'

= ing the threaded hole lli, is an arnn'ltl, havimproved Carpet Stretcher and Tacker, of

which the following is a full, clear, and exact description.

This invention relates Vto a nn-ichanisni for stretching and tacking carpets, and has for its object to provide an effective apparatus by means of which a carpet may be easily stretched and fastened down.

Reference to behad to the accompanying drawings, forming a part of this speeication, in which similar ligures f reference indicate corresponding' parts in all the views.

Figure l is a side view of the improvement with parts in section and parts broken away, illustrating' it in operative position. Fig. 2 is a plan view thereof. Fig. 3 is a detail view in vertical section, with parts broken away, oli' the tacking portion of the device. Fig. 4 is a rear view of-the tacking device. Fig. 5 is a front view thereof. Fig. `is a detail view, with parts in section on the line .r in Fig. l, ol the lever for operatingl the stretcher; and llig. 7 is a view representing the lacker dei ached with an operatingehandle supplied.

In the construction of this invention the stretcher consists of a main piece, l, formed of a bar ol' suitable length, on which is mounted and secured, by means of sleeves 2, a sliding bar, 3, having' its under side formed with a groove, el, in which lies a portion of an operating-cord, 5, secured to the inner end of the bar l and passing' through an opening, o, in the end of the bar 23, and then extending to a lever, 7, pivoted to a bucket, 8, on the bar 3, and held in adjustable position by means of a pivoted catch or pawl, 9, located in a recess, .l(),in the lever7. To avoid Friction, the opening (l may be ijn'ovded with a pulley, l l, over which the cord 5 passes.

The outer end of the bar 3 is provided with a head piece or frame, l2, in the shape ot' a [fork provided with. downwardly-bent plates l-", having a cross-piece, 13', which extends across the opening'of the forked head l2, said plates 123 having serrated ends 14. \\'ithin the forked head l2 is pivotcd a frame, l5, hav- .ingl a threaded hole, lli, and a perforated lng, 1.7. Vthin the perforated lug i7, and engaging' a threaded end, 1Q, engaging the hole 1G, and held in place by means of a set-screw, 20, in the top of the pivoted frame l5. The outer end of the arm 1S is formed in the sha-pe of a fork with serrated points 2l. The normal position of the forked arm il 8 corresponds with the position of the plates 1.3, bringing the serrated points 1li and 2l in line, the end of the pivoted :frame l 5 resting on the cross-piece 13.

Upon the forked end of the bar 1S is mounted a device for driving' tacks, consisting of a standard, 22, having' pivoted thereto the arms 23, the lower ends of which are formed with lilartlvclosed tapering' portions l, constituting together a casing for a tack, and the upper arms of which are fastened to the ends of the s]n.'ingwire arms Q5, acting by tension to keep the folded ends 2i in closed position. Upon the standard 22 is also mounted a bracket, 26, through which passes the tack-plunger 27, havinga fixed projection or flange, 28, and a coil-spring, encircling the plunger 27 and located between the dan ged projection Q8 and the lower projection, 30, of the bracket 2li, the upward movement of the plunger being limited by the ianged projection 2S abutting against the projection of the bracket 2G. The lower opening, 32, of the folded portions 24 projects between the arms of the forked end of the bar 1S. lt will be seen that by means of this construction a tack placed in the closed portions 2i will be held therein by means of its head, and upon the descent of the plunger 27 will be driven out through the opening 32 of the folded p 1 rtions 2.1, the head of the tack and the plunger separating' the said portions 24, which close automatically by the tension of the springs 'after the plunger has been withd rawn th eret'roln.

ln operating the stretcher the main piece l is placed on th c licor, with :its outer end abutting against the wall of the room, and the forked head l2, having been adjusted to the desired position, with the serrated points 14. and 2l pressing into the carpet, the cord 5 is fastened to the lever 7 by means of the pivoted catch 9, and the lever 7 is then pulled forward, thereby causin the bar 3 to be drawn forward on the bar l., which acts t0 stretch the carpet. A tack having been placed in the TOO folded portions 2l is driven into the carpet at the stretched point, as hereinbefore referred to, by means of the plunger 27.

If it be desirable to use the tacking device separately from the stretcher, it may be detached by unscrewing the set-screws 2O and arm 18, and it may then be used with a handle, 35, screwed on the threaded end 19 of the bar 18.

. While I have described a specific coi'istruction and arrangement of parts, I do not intend to limit myself thereto, as they may 1be varied without departing from the essential features of the invention.

Havin g thus described my invention, I claim as new and desire to secure by VLcaters Patent- 1. In a combined carpet stretcher and tacker, the combination, with a stationary bar and a slid inbarhaving a forked and serrated end, of a pivoted 'frame on the end of the sliding bar, a bar adjustably secured in the said frame, and a tacker carried on the end of the said bar, substantially as herein shown and described.

2. In a combined carpet stretcher and tacker, the combination, with a stationary bar, a slidingbar having a 'forked and serrated end, and means for operating the said sliding bar, of a pivoted frame on the forked end of the slidingI bar, a bar having a forked and serrated end and adj ustabl y secured in the pivoted frame, and a tacker on the forked end of the said adjustable bar, substantially as herein shown and described.

3. In a combined carpet stretcher and tacker, the combination of a stationary bar, a sliding' bar having a forked and serrated end, a lever pivoted to the sliding bar and provided with a catch, a rope secured to the stationary bar, passed under and through an aperture in the sliding bar and engaged by the catch on the said lever, a pivoted vframe on the forked end of the sliding bar, a bar ing lower ends, the spring-arms 25, for holding the arms 23 closed, the plunger 27, working in the bracket 2G, and the spring 29, surroundin the plunger, substantially as herein shown and described.

A combined carpet stretcher' and tacking mechanism, consisting of the main bar 1 and the extensible bar 3 sliding thereon, held together by means of the sleeves 2, the outer end of the sliding bar 3 being formed with a forked head, 12, having' the arms 13 and cross-piece 12:3 and serrated ends let, and the Aframe 15, pivoted in the forked head 12 and having mounted therein a bar, 18, secured by the set-screw 20, and formed with a forked end having serrated points 21, and a tackdriving mechanism consisting of a standard, 22, mounted on the forked end of the bar 18, and provided with pivoted arms 23,]1aving the lower tapering folded ends, 24, and the spring-arms 25, connected with their upper ends, and a springactuated plunger, 27, mou uted on the frame 22, together with means .for extending the sliding' bar 3, consisting of the cord 5,'fastened in the inner end of the bar 1, passing through a groove, 4, in the bottom of the bar 3, and an opening, G, in the end of the bar 3, and secured to a lever, 7 mounted on the bar 3, by means of a pivoted catch, 9, substantially as described.
